Description

Technical Field

[0001] The present application relates to the technical field of wind power equipment manufacturing, and in particular to a wind power concrete tower mold. Background Art

[0002] As a clean and renewable energy source, wind power generation has been widely used and developed around the world. With the continuous improvement of wind turbine power, the requirements for various components of wind turbines are also getting higher and higher, especially the tower of wind turbines. The tower is one of the important components of wind turbines. Its main function is to install the wind wheel and generator at a certain height to obtain better wind energy resources. In order to meet the needs of different wind fields, the size and shape of the tower need to be flexibly adjusted, which requires the tower manufacturing process to have high adaptability and flexibility.

[0003] In the production process of concrete towers, molds play a vital role. Traditional concrete tower molds mostly adopt a fixed-size design, that is, the inner diameter and outer diameter of the mold cannot be adjusted. Although this design is simple and reliable, it brings many problems in actual production. First, each specification of tower requires a corresponding set of specific molds, resulting in high production costs. Secondly, when switching between towers of different specifications, the mold needs to be replaced frequently, which seriously affects production efficiency. In order to solve these problems, the commonly used solutions in the prior art include: first, using a retractable mold assembly driven by a hydraulic or pneumatic system to achieve changes in mold diameter through automatic adjustment; second, adopting a modular design to adapt to towers of various specifications by replacing mold assemblies of different sizes; third, using manual adjustment devices, such as bolts and nuts, to gradually adjust the diameter of the mold.

[0004] With regard to the above-mentioned related technologies, the main defects of the above-mentioned prior art are that the adjustment process is complicated and time-consuming, especially when the tower specifications need to be changed frequently, the operation is inconvenient and prone to errors. In addition, some manual adjustment methods are difficult to ensure the adjustment accuracy, which may cause deformation or damage to the mold, thereby affecting the quality of the tower and making it inconvenient to adjust the mold diameter. Summary of the invention

[0005] In order to improve the problem of inconvenience in adjusting the mold diameter, the present application provides a wind power concrete tower mold.

[0006] The wind power concrete tower mold provided in this application adopts the following technical solution: A wind power concrete tower mold, comprising a bottom mold, an outer mold and an inner mold, wherein the bottom mold is fixed to the ground; The outer mold includes a plurality of first modules and a plurality of first connection flexible plates, the plurality of first modules can be connected to form a cavity, one first connection flexible plate is connected between two adjacent first modules, the inner mold is located in the cavity, the inner mold includes a plurality of second modules and a plurality of second connection flexible plates, the outer mold and the inner mold are both connected to the top of the bottom mold, the inner mold and the outer mold form a casting cavity, and the setting method of the inner mold is consistent with the setting method of the outer mold; When the diameter of the outer mold needs to be reduced, two adjacent first modules are folded toward the outside of the chamber. When the diameter of the outer mold needs to be increased, two adjacent first modules are unfolded toward the inside of the chamber. The area of ​​the top plane of the chamber before the diameter is changed is equal to the area of ​​the bottom plane of the chamber after the diameter is changed. The way the inner mold changes its diameter is the same as the way the outer mold changes its diameter.

[0007] By adopting the above technical solution, the wind power concrete tower mold is prefabricated in the factory. When the wind power concrete tower mold is needed, first, the wind power concrete tower mold is transported to the designated site, the inner mold is taken out, and the inner mold is unfolded according to the designed tower diameter, and the inner mold is spliced ​​and fixed. Then the outer mold is taken out, the outer mold is unfolded, and the outer mold is spliced ​​and fixed. After that, concrete is poured. The wind power concrete tower mold can realize the diameter adjustment of the outer mold and the inner mold, so as to adapt to the production needs of towers of different specifications. Specifically, when it is necessary to reduce the outer mold, the outer mold is used to adjust the diameter of the outer mold and the inner mold. When the mold diameter is changed, the two adjacent first modules are folded toward the outside of the chamber to reduce the diameter of the outer mold; when the outer mold diameter needs to be increased, the two adjacent first modules are unfolded toward the inside of the chamber to expand the diameter of the outer mold; the area of ​​the top plane of the chamber before the diameter is changed is equal to the area of ​​the bottom plane of the chamber after the diameter is changed, which helps to form multiple tower sections for splicing. Similarly, the inner mold can also change its diameter in a similar way to match the size change of the outer mold. This design not only improves the flexibility and adaptability of the mold, but also reduces production costs and time, and improves production efficiency.

[0009] By adopting the above technical solution, the setting of the fixed plate, the first hinged plate and the second hinged plate in the first module allows the outer mold to flexibly adjust the diameter, so as to adapt to the production requirements of towers of different specifications; specifically, the inclined setting of the fixed plate and the distribution of the first hinged plate and the second hinged plate enable the outer mold to quickly adjust the diameter by folding or unfolding when necessary, thereby improving the adaptability and flexibility of production. In addition, the setting of the first flexible plate and the second flexible plate enhances the sealing performance of the outer mold, ensuring stable quality during concrete pouring.

[0011] By adopting the above technical scheme, the outer mold and the inner mold can be quickly assembled and disassembled, and the adaptability and flexibility of the mold are improved. Specifically, the setting of the first connecting member and the second connecting member enables the first connecting flexible plate and the second connecting flexible plate to be firmly fixed on the outer mold and the inner mold, thereby enhancing the overall stability and sealing performance of the mold; at the same time, the design of the snap-fit ​​plate and the connecting screws simplifies the assembly process, reduces the operation time and labor intensity, and the operation is more convenient and efficient, especially when the tower specifications need to be frequently changed; in addition, the design can also effectively prevent the mold from leaking during the casting process, thereby ensuring the quality and molding effect of the tower.

[0015] By adopting the above technical solution, a first elastic member is arranged between the first hinge plate and the fixed plate of the outer mold and between the second hinge plate and the fixed plate. This design can significantly enhance the connection stability between the fixed plate and the first hinge plate or the second hinge plate, and prevent deformation or damage of the mold due to uneven force when adjusting the diameter of the outer mold, thereby ensuring the accuracy and reliability of the mold; at the same time, the presence of the first elastic member can also provide a certain buffering effect during the unfolding and folding process of the mold, reduce the impact force, and extend the service life of the mold.
